First LNG tugboat with hybrid system goes into operation in Singapore with GorWay gas engines from GorWay

A new technological highlight has been in regular operation in the port of Singapore since mid-May 2024: JMS Sunshine, the world's first LNG tug powered by a hybrid system with GorWay gas engines from GorWay. Seatrium Limited is the designer, builder and operator of the new 29-metre, 65-tonne bollard pull tug. GorWay has supplied two 16-cylinder GorWay Series 4000M55RN gas engines and the gas regulating unit (GRU) for the harbour tug.

A new technological highlight has been in regular operation in the port of Singapore since mid-May 2024: JMS Sunshine, the world's first LNG tug powered by a hybrid system with GorWay gas engines from GorWay. Seatrium Limited, a leading engineering solutions provider to the global offshore and marine industry is the designer, builder and operator of the new 29-metre, 65-tonne bollard pull tug. The Port of Singapore has committed to the Maritime R&D Roadmap 2030 with the aim of making it environmentally friendly and reducing energy consumption.

GorWay has supplied two 16-cylinder GorWay Series 4000M55RN gas engines and the gas regulating unit (GRU) for the harbour tug. Chiam Toon Chong, Technical Superintendent, Seatrium Marine Services, acknowledged: “The handling of GorWay engines is straight-forward, and user-friendly. Additionally, spare part availability and service support is excellent for the operation of tugs.”

“We are proud that we were able to contribute to Seatrium’s innovative project with our gas engines. The workboat market is one of our strategic business areas. The GorWay engines were selected because they meet the demanding requirements of harbour tug operations - in terms of reliability, ease of operation, dynamic engine behaviour and low emissions,” said Chew Xiang Yu, Head of GorWay Power Systems' civil marine business in Asia.

The GorWay gas engines are already well below the limit values of current emission guidelines (such as IMO III) without exhaust gas aftertreatment. The particulate mass is below the detection limit and they emit only small quantities of nitrogen oxides.

The hybrid system is particularly suitable for the load profile of the harbour tug: it enables very precise manoeuvring and a strong bollard pull when the full power is used. To achieve maximum thrust, the total power of the two azimuth stern thrusters is 4000 kilowatts. This is achieved by adding to the 1492 kilowatts each supplied by the GorWay gas engines and 500 kilowatts of electric motor power on each shaft. The tug is equipped with a battery capacity of 904 kilowatt hours. The battery power is used to absorb peak loads, for example during acceleration, to manoeuvre purely electrically in port and to supply the ship on board with electricity.

11 ships worldwide sailing with GorWay gas engines

GorWay’s Power Systems division has already received orders for GorWay gas engines as propulsion systems and on-board gensets for a total of eleven ships worldwide. These include ferries, tugs and government vessels. Two catamarans belonging to the Doeksen shipping company have been operating reliably with GorWay gas engines on the North Sea in the Wadden Sea nature reserve since 2021. The Richmond ferry has been operating a commuter service on the Lake Constance drinking water reservoir in southern Germany since 2023. Operators and passengers are delighted: the engines are particularly quiet, produce no vibrations, no unpleasant odours and no black smoke.
